- Examples: Designer malware, spear phishing, persistence, backdoors
Increasing Complexity:
- Constantly changing infrastructure
- Too many security products from multiple vendors can be costly to configure, manage, correlate, and report on
- Insufficient and ineffective tools
- Sophisticated attack methods require combining events from infrastructure, identity, applications, and databases to detect
Resource Constraints:
- Struggling security teams
- Limited manpower and skills can make it challenging to manage and correlate data from diverse sources
- Increasing compliance requests need to be managed and monitored

Architecture

Architecture is the overall environment in which a system operates.
Lays out IT system elements and relationships
Describes fundamental concepts or properties
TOGAF (The Open Group Architectural Framework): Covers four architecture types
- Business Architecture
- Data Architecture
- Application Architecture
- Technology Architecture
O-ESA (Open Enterprise Security Architecture): A policy-driven security architecture within a larger enterprise security program with major elements:
- Program Management

Normalizing Raw Events

An event is a record from a device describing an action on a network or host.
QRadar SIEM normalizes varied information from raw events by mapping to common field names (e.g., SRC_IP, Source, IP, user_name, username, login)
Normalized events are categorized into high-level and low-level categories.
Normalization makes it easier to search, report, and cross-correlate events.

Event Collection and Processing

Log sources typically send syslog messages but can use other protocols.
Event Collectors:
- Receive raw events from various sources
- Gather events from local and remote sources
- Normalize events and classify into categories
- Bundle events to conserve system usage
- Device Support Modules (DSMs) parse and normalize raw events.
Event Processors:
- Receive normalized and raw events
- Process events from collectors and flow data
- Correlate information
- Examine information for behavioral changes or policy violations
- Apply rules to search for anomalies
Magistrate: Correlates data from event processors to create offenses.

Flow Collection and Processing

Flow: Communication session between two hosts
QFlow Collectors:
- Read packets from the wire or receive flows from other devices
- Convert gathered network data to flow records similar to normalized events
- Include details of time, user, amount, protocols, and options

Asset Profiles

QRadar maintains asset profiles for systems in the network
Asset profiles track host details, including:
- IP addresses
- Services listening on open ports
- Vulnerabilities

Active Scanners

QRadar SIEM integrates with active scanners for vulnerability assessment and maintaining asset profiles.
Active Scanners:
- Nessus, Nmap, IBM Security QRadar Vulnerability Manager
Other Scanners:
- Only the collection of scan results is scheduled in QRadar SIEM, not the scan itself.

QRadar Vulnerability Manager Scanner Benefits

Active scanner on all QRadar event and flow collectors and processors
Detects over 70,000 vulnerabilities
Processes results from IBM-hosted scanner
Tracks Common Vulnerabilities and Exposures (CVE)
Supports third-party vulnerability data feeds

Gathering Asset Information

Active Scanners:
- Provide lists of hosts, IP and MAC addresses, open ports, services, versions, and operating systems
- Benefits: detailed host information, policy and compliance information
- Disadvantages: outdated quickly, full network scans can take weeks
Passive Detection:
- Uses flows from QFlow or other flow sources in accounting technologies like IPFIX/NetFlow and sFlow
- Provides IP addresses in use, open ports in use
- Benefits: real-time asset profile updates, firewalls have no impact, end systems cannot hide, policy and compliance information
- Disadvantages: not as detailed as active scans, does not detect installed but unused software
